Pinpointing the exact cause of cancer is extremely difficult because firefighters are not exposed to just one agent. They are exposed to multiple cancer-causing agents.

The video shows 15 simple actions that firefighters can take to minimize the risk from occupational exposure to fire ground contaminants.
